I'm new to the tubby game, what's up with a dv on efi?
It was on the car when I got it, thought it was a strange place to fit it too. It isn't that loud as I'm only running 3-4 psi until I get the ECU/MAP sensor etc fitted. My gf was running 19pis on her ERST and the DV was crazy loud!
Any particular kind of chip I would need for the chatter? Won't be doing that for a while though, gotta get her running sweet first
